-* PolyGerrit Fixes
+    Fixes a misconception that leads to data being accessible through Gerrit
+    APIs that should be locked down.
 
-* Documentation Updates
+    Gerrit had two components for determining if a Git ref is visible to a
+    user: `(Default)RefFilter` and `PermissionBackend#ForRef` (e.g.,
+    `RefControl`). The former was always capable of providing correct results
+    for all refs. The latter only had logic to decide if a Git ref is visible
+    according to the Gerrit `READ` permissions. This includes all refs under
+    `refs/heads` as well as any other ref that isn't a database ref or a Git
+    tag. This component was unaware of Git tags and notedb-related refs. Hence,
+    when asked for a database reference such as `refs/changes/xx/yyyyxx/meta`,
+    the logic would allow access if the user has `READ` permissions on any of
+    the ref prefixes (such as the default "read refs/* Anonymous Users").
 
-* Dependency Updates
+    That was problematic, because it bypassed
+    [documented behavior](http://gerrit-documentation.storage.googleapis.com/Documentation/3.2.5/access-control.html)
+    where a user should only have access to a change if he can see the
+    destination ref. The same goes for other database references.
+
+  * [Issue 13514](https://bugs.chromium.org/p/gerrit/issues/detail?id=13514):
+  Work around Gitiles bug on `All-Users` visibility.
+
+    Gitiles has a special `FilteredRepository` wrapper that allows carefully
+    hiding refs based on the project's ACLs. There is however an optimization
+    that skips the filtering in case a user has `READ` permissions on every ACL
+    pattern(s). When the target repository is `All-Users`, the optimization
+    turns into a security issue because it allows seeing all personal information
+    associated with all accounts, i.e.:
+
+    * draft comments
+    * draft edits
+    * personally identifiable information (PII) of all users
+    * external ids
+
+    This fix now blocks Gitiles or any other part of Gerrit to abuse this power
+    when the target repository is `All-Users`, where nobody can be authorized
+    to skip the ACLs evaluation anyway.
